Is it possible to use the Session-Timeout setting to force wireless clients to re-authenticate with the RADIUS server at a given interval? Unfortunately my Acesss Point does not provide this functionality, so I either have to do it via a supplicant such as the Funk Odyssey Client or on the Freeradius server. I am running Freeradius 1.1.3 on a Debian Sarge 3.1 system and I'm using EAP-TLS for authentication. I don't think it matters but I'm using a Buffalo WHR-G54S Wireless Router with the DD-WRT v23 SP2 firmware. I am trying to force my wireless clients to re-authenticate with the RADIUS server every 30 minutes (1800 seconds) with the Session-Timeout setting. Currently I am testing with just one user, and the Session-Timeout = 1800 setting is being sent with the Radius Access Accept message (I can see it in the Accept Accept message when I run in debug mode). However, this seems to have no affect. The user does not re-authenticate at the given interval. Here's my setting from the users file: "Jason Wittlin-Cohen" Session-Timeout = 1800
